Force in action 0.0 / 5 ? PhysicsForces and MotionGCSEAQA Created by: megan2001jCreated on: 07-03-17 20:20 What is the centre of mass? The centre of mass of an object is the point at which its mass may be thought to be concentrated. 1 of 9 What happens when an object is freely suspended? It will come to rest with is centre of mass directly beneath the point of suspension. 2 of 9 Give an example of an oscillation motion Motion of a swing 3 of 9 What is the amplitude of an oscillating object? The distance it moves from its equilibrium position 0 to its highest position A or B on either side. 4 of 9 What is the frequency of oscillations? The number of complete cycles of oscillations per second. 5 of 9 What factors will stop the oscillations if it is not pused continuously? Friction and air resistance 6 of 9 What is the moment of a force? A measure of the turning effect of the force on an object 7 of 9 How can the turning effect of the force(moment) of the force can be increased by: Increasing the size of the force, using a spanner with a longer handle 8 of 9 What does a principle of moment state for an object that is not turning? the sum of all the clockwise moments about any point=the sum of all the anticlockise moments about that point 9 of 9
